Description

Technical Field

[0001] The utility model relates to the technical field of joints, in particular to a non-overflow hydraulic quick joint. Background Art

[0002] In hydraulic systems, quick connectors are an important connection component that does not require the use of tools and can quickly install and disassemble pipelines. They are widely used in various hydraulic pipelines to connect or disconnect pipelines.

[0003] Traditional hydraulic quick connectors are usually connected by threaded connection or clamp connection, but these connection methods are prone to loosening and leakage when used for a long time or subjected to external force. Therefore, we propose a non-overflow hydraulic quick connector to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art hydraulic quick connectors that use threaded connections or clamp connections, which are prone to loosening and leakage when used for a long time or subjected to external force impact, and to propose a non-overflow hydraulic quick connector.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A non-overflow hydraulic quick connector, comprising a male buckle and a female buckle, wherein one end of the male buckle is fixedly connected to a liquid inlet pipe, and one end of the female buckle is fixedly connected to a liquid outlet pipe. Four fixing blocks are fixedly provided on the outer side of the male buckle at equal intervals, and the outer walls of the four fixing blocks are connected to the same fixing ring. The inner wall is provided with notches corresponding to the four fixing blocks, and the four fixing blocks are respectively slidably connected to the inner walls of the corresponding notches. Two limiting holes are symmetrically provided on the fixing ring. The connector also includes:

[0007] A connecting assembly is provided at one end of the male buckle and the female buckle, and is used to connect the male buckle and the female buckle;

[0008] The limit assembly is set on the female buckle to prevent the male buckle and the female buckle from loosening when connected.

[0009] In one possible design, the connecting assembly includes a connecting tube, which is fixedly arranged at the end of the male buckle away from the liquid inlet pipe, and two clamping blocks are symmetrically arranged on the outside of the connecting tube, and the two clamping blocks are fixedly connected to the male buckle, and the two clamping blocks are inclined surfaces. The end of the female buckle away from the liquid outlet pipe is provided with a clamping groove corresponding to the two clamping blocks, and limiting grooves are provided in the two clamping grooves. One side of the inner wall of the two limiting grooves is provided with an inclined surface corresponding to the clamping block, and the clamping block is clamped with the limiting groove.

[0010] In one possible design, a limiting ring is provided on the inner wall of the female buckle, and a first groove is provided on the side of the limiting ring close to the limiting groove. An anti-overflow rubber pad is fixed in the first groove, and one end of the connecting tube conflicts with the anti-overflow rubber pad.

[0011] In a possible design, two rubber rings are fixedly provided on the inner wall of the female buckle, and two second grooves corresponding to the rubber rings are opened on the outer wall of the connecting tube, and the two rubber rings are located in the corresponding second grooves.

[0012] In a possible design, the limit assembly includes two limit columns, and two sliding grooves corresponding to the limit holes are symmetrically opened on the female buckle. The two limit columns are respectively slidably connected to the corresponding inner walls of the sliding grooves. The bottoms of the two limit columns and the bottom inner walls of the corresponding sliding grooves are fixedly connected with the same compression spring. The limit columns are inserted into the corresponding limit holes, and the end of the limit column away from the compression spring is arc-shaped.

[0013] In a possible design, the inner walls of the liquid inlet pipe and the liquid outlet pipe are both provided with threads for facilitating connection with an external pipe.

[0014] In this application, when it is necessary to connect the hydraulic pipeline, first align the male buckle and the female buckle so that the block on the connecting pipe corresponds to the slot on the female buckle, and then rotate the male buckle so that the block gradually slides into the limit groove along the inclined surface of the slot to achieve the connection between the male buckle and the female buckle. At the same time, one end of the connecting pipe contacts the anti-overflow rubber pad on the limit ring on the inner wall of the female buckle, ensuring the sealing of the connection. At the same time, the rubber ring on the inner wall of the female buckle corresponds to the second groove on the connecting pipe, further enhancing the tightness and stability of the connection.

[0015] After the connection is completed, compress the two limit columns so that they retract into the corresponding sliding grooves, then move the fixing ring so that it slides on the four. After the fixing ring moves to the specified position, the two limit columns sliding in the sliding groove on the female buckle move upward due to the action of the compression spring, and the limit columns will be inserted into the limit holes on the fixing ring, realizing the locking and anti-loosening of the male buckle and the female buckle after docking.

[0016] Beneficial effects:

[0017] In the present invention, the overflow-free hydraulic quick connector achieves a tight connection between the male buckle and the female buckle through the cooperation between the clamping block and the clamping groove in the connection assembly, thereby effectively preventing the occurrence of leakage.

[0018] In the present invention, the non-overflow hydraulic quick connector ensures the sealing of the connection by causing one end of the connecting pipe to come into contact with the anti-overflow rubber pad, thereby further improving the performance of non-overflow.

[0019] In the present invention, the overflow-free hydraulic quick connector effectively prevents loosening after connection through the design of the limit assembly, thereby ensuring the safety and reliability of the connector;

[0020] In the utility model, the cooperation between the card block and the card slot in the connecting component is used to achieve a tight connection between the male buckle and the female buckle, effectively preventing the occurrence of leakage. By having one end of the connecting pipe contact the anti-overflow rubber pad, the sealing of the connection is ensured, and the performance of no spillage is further improved. The design of the limit component effectively prevents loosening after connection, ensuring the safety and reliability of the joint. BRIEF DESCRIPTION OF THE DRAWINGS
